MSI MS-C926 ultra-slim, fanless industrial box PC is just 19mm thick

MSI MS-C926 is an Intel Alder Lake-N/Twin Lake fanless industrial box PC that’s ultra-slim at just 19mm thick, making it suitable for space-constrained applications such as digital signage, industrial control, kiosks, and edge computing.

This ultra-thin PC also features up to 16GB DDR5 memory, triple 4K display outputs, dual 2.5GbE, three USB 3.2 Gen 1 ports, and a COM port. Expansion options include an M.2 B-Key slot with Nano SIM support for cellular, an M.2 E-Key slot for Wi-Fi, and a 2.5-inch SATA drive bay. It also supports optional TPM 2.0, a wide 12–24V DC input, VESA/wall mounting, and operates between -10°C to 50°C.

The MS-C926 supports Windows 11 IoT Enterprise LTSC (64-bit, 24H2) and Windows 10 IoT Enterprise LTSC (64-bit, 21H2) for Alder Lake-N platforms. They also mention Linux support is available upon request. Other than that, not much information is available about the product. The company mentions that the device supports 5G/LTE via nano SIM, but that SIM socket must be inside, potentially under the Key-B module, as there is no obvious opening to insert a Nano SIM card.

We have written about other compact and slim form factor PCs in the past, including the MeLE Overclock X2 and the Palmshell SLiM X4L, but those are actively-cooled, while the MSI MS-C926 is fanless and has more features.

The company did not provide pricing information, but we can see the MS-C926 listed on at least two European distributors: Elmark Automation and Rosch Computer, sadly without public pricing information, but at least those are places to ask. Additional information can be found on their products page.
